摘　　要：为了改善套料电解加工的锥度问题,针对圆柱状工件开展了有、无绝缘套的电解加工对比仿真,结果显示,采用绝缘套后工件锥度改善明显,但仍存在一定的锥度。为进一步减小加工锥度,开展了不同线性变电压参数下的套料电解加工仿真,结果显示,工件锥度随着变电压斜率的增大而逐步减小。为验证仿真的准确性,开展了不同斜率的变电压套料电解加工试验,结果表明,在17~23 V电压下加工的工件锥度最小,这与仿真结果一致。In order to improve the taper problem in electrochemical machining of the jacketed material,a comparative simulation of electrochemical machining with and without an insulating sleeve was carried out for cylindrical workpieces.The result showed that the taper of the workpiece was improved significantly after insulating sleeve was used,but a certain taper still exists.In order to get a further reduce for processing taper,the simulation of jacketed electrochemical machining under different linear variable voltage was carried out.The result showed that the workpiece taper gradually decreases with the increase of the variable voltage slope.Furtherly,In order to verify the accuracy of the simulation,jacketed electrochemical machining experiments with variable voltage of different slopes were carried out.The results showed that workpiece processed at 17~23 V got the smallest taper,which is consistent with the simulation results.
